ÏM = standard error of the mean Ï = the standard deviation of the original distribution N = the sample size âN = Root of the sample size. The standard error of the mean, also called the standard deviation of the mean, is a method used to estimate the standard deviation of a sampling distribution.To understand this, first we need to understand why a sampling distribution is required.

Acidosis and alkalosis describe the abnormal conditions that result from an imbalance in the pH of the blood caused by an excess of acid or alkali (base).
This condition results when the buffer base (bicarbonate ions) is greater than normal and the concentration of hydrogen ions are decreased. Both acidosis and alkalosis can be of two different types: respiratory and metabolic. Respiratory acidosis or alkalosis is caused by various malfunctions of the lungs. Metabolic acidosis or alkalosis is caused by various metabolic disorders which result in an excessive build up or loss of acids or bases.
